Store Data In Remote DataBase Using cUrl or Execute a HTTP POST Using PHP CURL

The information isn’t going to be saved on the localhost database — it needs to be stored in a remote database that I cannot connect directly to.I thought about all of the possible solutions for solving this challenge and settled on this flow:

1. User will submit the form, as usual.
2. In the form processing PHP, I use CURL to execute a POST transmission to a PHP script on the customer’s server.
3. The remote script would do a MySQL INSERT query into the customer’s private database.

This solution worked quite well so I thought I’d share it with you. Here’s how you execute a POST using the PHP CURL library.

1. //extract data from the post
   extract($_POST);
   
   //set POST variables
   $url = 'http://mydomain.com/postpage.php';
   $fields = array(
   						'lname'=>urlencode($last_name),
   						'fname'=>urlencode($first_name),
   						'title'=>urlencode($title),
   						'company'=>urlencode($institution),
   						'age'=>urlencode($age),
   						'email'=>urlencode($email),
   						'phone'=>urlencode($phone)
   				);
   
   //url-ify the data for the POST
   foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
   rtrim($fields_string,'&');
   
   //open connection
   $ch = curl_init();
   
   //set the url, number of POST vars, POST data
   curl_setopt($ch,CURLOPT_URL,$url);
   curl_setopt($ch,CURLOPT_POST,count($fields));
   curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
   
   //execute post
   $result = curl_exec($ch);
   
   //close connection
   curl_close($ch);

   Thanks
